Abstract: PURPOSE:To improve productivity and lower costs by adding a small amt. of a cellulosic thickener in producing a catalyst for removal of harmful gases such as CO by molding a metallic oxide catalyst and heat resistant aggregate with calcium aluminate as a binder. CONSTITUTION:As a catalyst for purification of gases contg. harmful components such as CO and hydrocarbons by oxidation, a cellulosic thickener such as methyl cellulose, methyl ethyl cellulose or the like is mixed at 0.1-1.0wt% with a mixture of, for example, 40-60wt% metallic oxide catalyst such as MnO2, 10-30wt% heat resistant aggregate such as SiO2 and 20-40wt% calcium aluminate as a binder. Water is added at 20-30pts.wt. to 100pts.wt. this mixture, and these are thoroughly kneaded and the mixture is molded to a honeycomb shaping having a large number of vent holes. This molding is placed on porous planking and is set in an atmosphere of 50-90 deg.C and 80% relative humidity, after which water is added thereto and the molding is cured. Since the releasing of this molding from honeycomb dies can be made in a short time by the use of the thickener, productivity is improved.

Title: Lightening-resistant bushing
Inventor: KAKO ISAO
IPC: H01T1/16
Filed: 1999-01-07
Abstract: PROBLEM TO BE SOLVED: To reduce the load of zinc oxide element against the lightening- resistant mechanism and improve the protection mechanism by providing an inside electrode forming a gap in a space toward the central conductor in the internal circumferential face of an annular zinc oxide element body provided as surrounding a central conductor transmitting an electric power to a power supply device by penetrating a bushing mounted to the tank of the power supply device. SOLUTION: When an abnormal voltage such as a lightening impulse, etc., is applied between an central conductor 4 and an earth connected to a tank 1, discharge starts toward an inside electrode 6B of a zinc oxide element 6 through a series gap 11 set at a prescribed clearance from the central conductor 4. Secondly, overcurrent flows radially from the inside electrode 6B toward an outside electrode 6C via the body 6A so as to be discharged from the outside electrode 6C via a lead wire 7 and a tank 1 to the earth. The lightening resistance mechanism of the lightening resistance bushing can be thus distributed between the zinc oxide element 6 and the series gap 11 so that the discharge voltage of the zinc oxide element 6 can be suppressed to low and the lightening resistance mechanism can be improved.

Title: Integrating wattmeter
Inventor: JIYON SUPENSUREI FUIIRUDEN
IPC: G01R21/00
Filed: 1980-01-10
Abstract: To detect tampering of a kilowatt-hour meter by the connection of a bypass link across the live connection through the meter, a voltage transformer within the meter unit is coupled to this live connecton so that a small volage is induced in the live connection in opposition to the supply voltage. The induced voltage produces a circulating current in the loop formed by the live connection and the bypass link and the transformer coupling is such that, with a bypass link of negligible resistance, the total current in the live connection is in opposite phase to the applied voltage. By means of a current transformer, a logic unit and a microprocessor, the phase of the current in the live connection within the meter is determined and is indicated by a latched flag indicator and/or transmitted to a distant data processor by a data link. Using a second current transformer in the return supply lead, the supply and return currents in the leads within the meter unit can be compared in the logic unit and processor to determine if the live connection is broken within the bypassed length. By means of contacts on the housing, indication is given if the housing of the unit has been opened.

Title: Controlling method of optical interface device and cassette device
Inventor: HIRATA OSAMU
IPC: H04B10/54
Filed: 1983-01-12
Abstract: PURPOSE:To improve reliability without any influence of electric disturbance and to perform remote control over a cassette device by performing optically interface control between equipments. CONSTITUTION:The output data signal OD of a personal computer is inputted to a transmission part 5 and a pulse signal OP with specific width appears synchronously every time the signal OD is inverted. The transmission part 5 further inputs a carrier pulse signal CP and an AND gate 54 passes the signal CP only when the signal OP is true, outputting a pulse signal MCP. The signal MCP turns on and off a transistor (TR)Q1 to output a pulse signal OCP of light from a light emitting diode 8. When the signal OCP is inputted to the photodiode 9 of a reception part 7, a ligh current flows through the resonance circuit of a coil L and a capacitor C3, and when this resonance frequency corresponds to the signal CP, an optical disturbing signal is removed to extract a carrier pulse signal RMCP similar to the signal MCP.

Abstract: PURPOSE:To provide high productivity, improve heat-exchanging efficiency and reduce noises. CONSTITUTION:Each heat exchange element 12 is formed by providing upright a plurality of spacing plates 19 on one face side of a gap plate 17 to form passages 22 and by sticking fast a partition 18 having moisture permeability to the other face side of the gap plate 17 to which the base parts of the spacing plates 19 are connected by connecting parts 20 so as to provide openings 21. Further, a stack body 13 is formed by stacking the heat exchange elements 12 so that the passages 22 are alternately intersected with one another. Accordingly, the spacing plates 19 are integrally connected to one another at their base parts by the connecting parts 20, and even the spacing plates 19 thin in thickness can be simply provided upright, whereby the heat exchange elements 12 having a sufficient strength can be favorably manufactured. On the other hand, the partition 18 is exposed to the passages 22 at the portions of the openings 21, and heat-exchanging can be carried out without hindrance. The spacing plates 19 thin in thickness have small impingement areas against a fluid, and noises are thereby reduced. Further, pressure drop in the passages 22 becomes small, and the connecting parts 20 act as a turbulent flow promotion part, whereby heat-exchanging efficiency is improved.
